The occurrence of diseases in sheep and goats is common in several regions of Brazil. Among these, ovine brucellosis has been studied and analyzed through serological surveys over the years. The serological diagnosis normally performed in the research is through the following methods, Complement Fixation Reaction (FC), Immunodiffusion in Agarose Gel (IDGA) and Immunoenzymatic Assay (ELISA-i). Comparisons in the concordance of these tests indicated a variation in the results leading to consider the presence of related diseases of the reproductive system and Pododermatitis, besides the types of antigens used in the serological tests that can interfere in the immune response. Therefore, correlating the serology to the confirmation of the agent isolation or by PCR and the improvement in the quality of the antigen (s) used becomes necessary. [ABSTRACT FROM AUTHOR]
